How to integrate Twilio with GoHighLevel (2026 guide)

Why connect Twilio to GoHighLevel

GoHighLevel has built-in messaging, but many businesses want Twilio for its reliability, number options, and advanced voice features. Integrating the two means your texts and calls flow through the same workflows that already handle your leads.

Step 1: Register for A2P 10DLC

Before any business SMS will deliver reliably in the US, you need A2P 10DLC registration, brand and campaign registration with the carriers. Skip this and your messages get filtered or blocked. It is the single most important step.

Step 2: Connect your Twilio messaging service

Create a messaging service in Twilio, attach your registered numbers, and connect it to GoHighLevel through the integration or webhook routing so inbound and outbound messages sync.

Step 3: Route voice and IVR

For calls, point your Twilio number's voice webhook to your IVR or routing logic, then log the call back into GoHighLevel so it triggers the right workflow, follow-up, or task.

Step 4: Test end to end

Send a test text and place a test call, and confirm each one appears in GoHighLevel and fires the automation you expect. Testing every path is what separates a setup that works from one that quietly drops leads.
